Percy Duncan Haughton (July 11, 1876 – October 27, 1924) was an American football and baseball player and coach.

Haughton was also Harvard's head baseball coach in 1915[1] and part owner of the Boston Braves from 1916 to 1918.

[3] Apocryphal tales assert that before the 1908 Harvard–Yale Game, Haughton strangled a bulldog in the locker room to motivate his players.

[6] After Haughton's military service ended, he announced he would not return to Harvard, instead focusing on his work with White Weld & Co.[7] Haughton became Columbia's football coach in spring 1923 as the school re-established a team that had been dissolved in 1905 following allegations that football had become too violent.

To alleviate concerns that the game was still too violent, Haughton promised to instil discipline in his players, saying: "It will be my purpose to teach the men what they should learn in order to better prepare for life after the university.
